AUGUST L. TVARGKMEISTER, OF NEWARK, NEW JERSEY, ASSIGNOR TO CHARLES A. WHARTON, OF SAME PLACE.

ROLLER SIZING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,565, dated February 14,1882.

Application filed May 31, 1881. (No model.)

To all whom it may concern:

Be it known that 1, AUGUST L. WARCKMEIS- TEE, a subject of the Emperor of Germany, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Roller Sizing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention relates to an improvement in roller sizing-machines of the class commonly employed in sizing hats by rollinga bundle of them, wrapped in a cloth, in the cavity between three or four such rollers.

The object of the invention is to fit the machine for operating on felt rolls of different sizes with more facility than in prior machines, and to dispense with the treadle commonly employed in connection with a swinging rollerframe to open the aperture between the rolls for the introduction and removal of the felts.

The invention is for the same subject-matter as a caveat filed by me on May 7, 1881, and further improvements perfected by me; and it consists, first, in a novel means of supporting, adjusting, and operating the movable roll in a three-roller sizing-machine; 'also,-in a new arrangement for the third roller below the pair of rolls between which the bundles oft felts are laid to be rolled and pressed, in lieu of the common arrangement above them in a swing-frame; also, in a novel mode of varying the size of the aperture between the three rollers in a machine having the third roller arranged at the bottom by making one or both of the horizontally-arrangedpair movable in place of the third roller.

In the drawings annexed, Figure l is a longitudinal sectional elevation of a three-roller ers to introduce a roll of hats, as well as to remove them, I having discovered that a proper adjustment of the rollers will afford the requisite pressure upon the felt roll and still permit its removal from or insertion in the space between them. This discovery affords an opportunity to arrange and adjust the rollers to felt bundles of various qualities and sizes in a very different manner from that hitherto employed, which was, viz., the mounting of one or a pair of rollers in a swinging frame which was operated byatreadleto insert and remove the felts. My machine thus exhibits, when in use, three rollers revolving in stationary bearings, with an aperture between them all, into which the felt bundles are thrown or removed by the operator without changing the position or relation of any of the rollers.

In construction the machine may present means of adjustment applied to any of the three rollers, that they may be set at suitable distances apart to roll and press the bundles of felt, which vary in size with the quality, weight, and numberof hats rolled together in one cloth.

To exhibit some of the modifications of which my invention is capable I have shown two modes of construction in the annexed drawings, in which A is the frame of the machine.

chine for wetting the felts, a shelf or plank being partly shown in Fig.1,upon which the hats are rolled and wetted.

O is the front roller ofthe principal pair; 0, the rear roller; D, the roller arranged above the rollers 0 G; E, the roller arranged below them; 11, the adjustable boxes ofD c, a screw for moving and setting the roller D at any required distance from O G c, the fixed hearing of the lower roller, E; c c, the adjustable boxes of the rolls 0 O; b, the right-and-lefthand screw, arranged to move them simultaneously to and from one another; f, a crank to operate such screw, and g a crank to operate the screw a.

G G are gears arranged to drive the rollers G G and D, the shaft of one gear being provided with pulleys H, and the movement of the gear on the adjustable roller being com- B is the tank, commonly supplied to the mapensatcd by an intermediate wheel upon a hinged link, as shown at I, or in any other suitable manner.

G G are gears arranged upon a similar link,

I, and upon the rollers O O in the machine shown in Fig. 3, and H the pulleyin the same arrangement. A gear, K, is also shown in the same figure applied to the shaft of the lower roller, E; and, if preferred, the pulleys may be applied to this gear and the rollers O O driven by it if the gears on all three rollers are provided with expansion teeth like those employed upon adjustable rollers in other machines.

The adjustable boxes of the upper roller, D,

are shown fitted. to vertical housings h, and the heads of the screws a are shown provided with grooved wheels t' and connected by a cord, J, to turn them simultaneously.

Chain may be used in place of the cord J, or gear-wheels connected by a horizontal shaft, and the same may be supplied with a shaft extending to the front of the machine, where it may be readily operated by the workman when desired.

The operation of my machine is the same whether the construction shown in Fig. 2 or 3 be employed, the operator rolling his felts in a bundle upon the plank in the usual way, and throwing the roll thus formed into the cavity between the three felting-rollers, where it is rolled and pressed in the same manner and with the same effect as in the roller-machines provided with movable rollers.

The arrows shown in thedrawin gs indicate the direction in which the various rollers revolve, and as the front roller, 0, is preferably revolved to carry the felts inward, they are readily retained in the cavity when placed therein, the other two rollers operating upon the felts tending to rotate them in the same direction. When arranged above the two principal rollers the upper roll, D, is preferably set nearer to the rear roller, 0, that the space between them may be smaller than the front space by which the felts are introduced. The felts are thus prevented from escaping through the rear space should they be carelessly thrown into the rollers and such space be large enough to give them exit.

In Fig. 1 I have shown the rollers O G and D provided each with six auxiliary rollers, 'r, embedded in their surface. Such rollers are described in a patent allowed to me on May 13, 1881, and are so mounted in the surface of the main roller as to revolve freely when in contact with the felts. They therefore aid very materially in permittingthe removal of the felts from the grasp of the three rollers between which they are placed. Such removal is effected by inserting the hand between therollers at one end of the felt-bundle and pulling the bundle outof the rollerswhile in motion. After crozing in the usual way upon the plank the bundle is replaced between the rollers, which are operated continuously so long as the process is continued.

From the above description it will be seen that my improved arrangement and mode ofoperating the three rollers relieves the workman entirely from the management of atreadle or other means employed to open the rollers every time afelt-bundle is i'nserted or removed therefrom. His attention can therefore be devoted entirely to the manipulation of the felts, and a greater number handled successfully in the same amount of time.

Having thus fully described my invention, Idonotlimitmyself to the precise means shown and described herein for carrying it into practice, but claim the same as follows:

1. The combination,in a roller hat-sizing machine, of three rollers adjusted at suitable distances to felt a bundle of hats by rolling and pressing it in the cavity between them, the

felts being inserted into and removed from the cavity without altering the distances of the rollers, substantially as herein described.

2. Thecombination, in a roller hat-sizing machine, of one felting-roller mounted in vertically-adjustable boxes in housings over two felting-rollers revolving in fixed bearings, the upper roller being located nearer to the rear roller than to the front roller, for the purpose set forth, and the felts being inserted into and removed from the cavity without altering the distances of the rollers, substantially as herein set forth.

3. The combination, in a machine having felting-rollers operated in fixed positions, as herein described, of the anti-friction rolls 1* with the main felting-rollers, to remove the resistance of the main rollers to the removal of the felts from the cavity between them.

. In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
